opera and javascript debugging

Hallo,

is it possible to add some commands to javascript, so that
it outputs the content of arrays into the
javascript-console?
something like
dump(array);
I know how to output single variables, but I don't see how
to do that with arrays.

thanks for input .-)

Hello Jurgen,
I'm a bit late so perhaps you've realised already but..

1) Normal arrays will print out as a comma-separated list of
values 
if you just do 

opera.postError(array)

2) Objects (with name=>value like other languages
sometimes call 
associative arrays) can be "inspected" with some
simple for..in 
tricks.


function objinspect(obj){var s='';for(var e in 
obj)s+=e+':'+obj[e]+'\n';opera.postError(s);}

objinspect(object)

Hope this helps.

thank you, yes it helps . I didn't
find out about the second option.  Have to save that.
